I would like to dye a pair of compression stockings. The content is 69% Poltmide & 31% Elasthane. I think that might be spandex and Lycra? Can I just use the Jacquard Acid Dye ? I probably won't be able to heat set.Thanks,Gale

Because the Acid dye needs considerable heat to work effectively I'd be concerned about both components of the stockings. You might want to consider using Dye-Na-Flow to color them instead. Using that light weight paint with Air Fix would eliminate the need for heat setting.
